Features of BV electric wire
BV electric wires is called copper core PVC insulated wire,that is, ordinary single-core hard conductor without sheathing cable, which is used in our daily life of ordinary insulated wire, home improvement wire, is the most commonly used type of the electric wire.
This product is made of high quality oxygen-free copper and environmentally friendly PVC, the performance of the products are in line with national standards GB / T5023.3-2008 / IEC60227-3: 1997.
With anti-acid-base, oil resistance, moistureproof, mouldproof and other characteristics.
Species of BV electric wire
Divided into ordinary, flame retardant, fire-resistant.
Ordinary: For residential, commercial buildings and industrial power distribution circuit (BV)
Flame retardant: In order to prevent the secondary fire spread as a target (ZR - BV, the ZA - BV, ZB - BV, ZC - BV)
Fire-resistant: Fire-fighting system (NH - BV)
The long-term permissible operating temperature of all types of cables shall not exceed 70 ℃. The laying temperature of the cable shall not be less than 0 ℃. The outer diameter (D) is less than 25 mm cable allowed bending radius should not less than 4D. The outer diameter (D) of 25mm and above the allowable bending radius of cable should not be less than 6D.
Application of BV electric wire
This product is suitable for AC rated voltage 450 / 750V and below, requiring the use of fire-retardant occasions of electrical, instrumentation, telecommunications equipment, power equipment and lighting lines fixed laying.
Model of BV electric wire
1.BV electric wires according to the conductor cross-sectional area can be divided into 01,05,07 three models, different models have different characteristics:
| BV Classification | |||||
| Model | Academic name | Insulation materials | Model specification | Rated voltage | Application |
| BV01 |
Copper Core PVC Insulated Wire |
PVC | General purpose single core hard conductor unshielded cable | 450/750V | Power equipment, household appliances, instruments and telecommunications equipment |
| BV05 | Copper Core PVC Insulated Wire | PVC | The internal wiring,Single core solid conductor unshielded cable with a conductor temperature of 70 ℃ | 300/500V | |
| BV07 | Copper Core PVC Insulated Wire | PVC | The internal wiring,Single core solid conductor unshielded cable with a conductor temperature of 90 ℃ | 300/500V | |
2.BV electric wires according to the different properties, the product can be divided into insulation, flame retardant, fire-resistant three categories, different uses of different categories:
